My age right now is a prime number. My age is greater than the number of kilometres in a marathon. Soon I will be turning X, where X is the product of a perfect square, and a prime number. Can you determine how old I will be turning?

My bicycle trip with my dad, no car, just 560 kilometres of travel completed by leg power was a complete success. My dad is at a “significant milestone” in his age – he was able to do 8 kilometres for each year he is old. He was stoic in silently suffering some discomfort in the region of the Ischial Tuberosity.
